scuba 1.2-1
** now with added Helium **
'scuba' is a contributed R package that performs theoretical calculations
about scuba diving --- dive profiles, decompression models,
gas toxicity and so on.
New features in version 1.2-1:
. Breathing gases may now contain Helium
as well as Oxygen and Nitrogen.
. Decompression models now handle breathing gases
containing Helium.
. Haldane (diffusion compartment) models are now
represented by objects of a special class "hm".
. Dive profiles (objects of class "dive") can be
modified more easily. You can change the breathing gas,
modify the depth and duration of a dive,
or cut-and-paste several dive profiles.
. Bug fix in showstates().
New functions:
ndl Calculates No-Decompression Limits
trimix Creates a gas object representing trimix
(oxygen/nitrogen/helium mixture)
hm Creates a new Haldane model (diffusion compartment model
for decompression theory).
pickmodel
Selects one of the standard Haldane models.
tanklist
tanklist<-

chop.dive
